Description

Technical Field

[0001] This utility model relates to the field of mobile phone charger technology, and more specifically, to a mobile phone charger based on a flyback topology. Background Technology

[0002] The flyback topology is a common switching power supply topology, typically used in low-power applications such as adapters and power converters. Its operating principle is based on the energy storage and transfer of a transformer. In a flyback topology, the input voltage is applied to the primary winding of the transformer through a switching device (usually a MOSFET). When the switching device is turned on, the current increases, and magnetic energy is stored in the transformer core.

[0003] Mobile phone chargers can be broadly categorized into travel chargers, desktop chargers, and maintenance chargers, with most users primarily encountering the first two types. Travel chargers are the most commonly sold type on the market.

[0004] With the development of technology, some mobile phone chargers also have flyback topology internally. However, some existing mobile phone chargers based on flyback topology have weak functionality. They can charge the phone when in use, but can only be placed there when not in use, and cannot expand the functionality of the mobile phone charger. Therefore, we provide mobile phone chargers based on flyback topology. Utility Model Content

[0005] The purpose of this invention is to provide a mobile phone charger based on a flyback topology to solve the problems mentioned in the background section.

[0006] Some existing mobile phone chargers based on flyback topology have limited functionality. They can charge the phone when in use, but can only be left unused when not in use, and cannot expand the functionality of the mobile phone charger.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A mobile phone charger based on a flyback topology includes a charger body with a mobile phone SIM card slot on its upper surface. A first rotating rod is rotatably connected to each of the corresponding two sides of the charger body. A first support plate is rotatably connected to the outer end of the first rotating rod away from the charger body. A second support plate is rotatably connected to the bottom of the first support plate. A second rotating rod is rotatably connected to each of the corresponding two sides of the first rotating rod outside the first support plate. The second rotating rod is rotatably connected to the charger body.

[0009] Preferably, the second rotating rod has the same length as the first rotating rod.

[0010] Preferably, a first gear is fixedly connected to the end of the first rotating rod near the second support plate, and a second gear is fixedly connected to the side of the second support plate near the first rotating rod, with the second gear meshing with the first gear.

[0011] Preferably, the charger body has a plug rod slidably connected inside, and one of the second rotating rods has a slot inside, which is used in conjunction with the plug rod.

[0012] Preferably, a baffle is sleeved on the outside of the plug rod and located between the charger body and the second rotating rod, the baffle is fixedly connected to the plug rod, and a spring is sleeved on the outside of the plug rod and located between the charger body and the baffle.

[0013] Preferably, a pull rod is fixedly connected to the outer end of the insertion rod away from the spring, and a groove is formed inside the pull rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The first support plates on both sides of the charger body unfold outwards. When the first support plates unfold outwards, they will drive the first rotating rod and the second rotating rod to rotate outwards. When the first rotating rod rotates outwards, it will drive the second support plate below the first support plate to rotate outwards through the first gear and the second gear. Since the first support plate has already expanded the bottom support area by unfolding outwards, the bottom support area can be further expanded as the second support plate also rotates outwards. Finally, insert the plug into the slot on the second rotating rod, put the phone into the SIM card slot, and the charger body can be used as a phone stand. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 A mobile phone charger based on a flyback topology includes a charger body 1. A phone slot 2 is formed on the upper surface of the charger body 1, which is used to place a mobile phone, allowing the charger body 1 to function as a phone stand. First rotating rods 3 are rotatably connected to corresponding sides of the charger body 1. A first support plate 4 is rotatably connected to the outer end of the first rotating rod 3 away from the charger body 1. A second support plate 5 is rotatably connected to the bottom of the first support plate 4. Second rotating rods 6 are rotatably connected to the outer side of the first support plate 4 and to corresponding sides of the first rotating rod 3. The second rotating rods 6 are rotatably connected to the charger body 1. When the first support plate 4 and the second support plate 5 are unfolded, they can cooperate with the first rotating rod 3 and the second rotating rod 6 to support the charger body 1, resulting in a larger support area for the charger body 1 and ensuring overall stability.

[0023] Furthermore, the second rotating rod 6 is the same length as the first rotating rod 3, and the first rotating rod 3 and the second rotating rod 6 are parallel to each other. This ensures that the first support plates 4 on both sides of the charger body 1 are always parallel to the charger body 1, allowing the first support plates 4 to unfold more smoothly.

[0024] Furthermore, a first gear 7 is fixedly connected to the inside of the first rotating rod 3 near the end of the second support plate 5, and a second gear 8 is fixedly connected to the inside of the second support plate 5 near the side of the first rotating rod 3. The second gear 8 meshes with the first gear 7. Under the action of the first gear 7 and the second gear 8, when the first support plate 4 is unfolded, it can also drive the second support plate 5 below the first support plate 4 to unfold as well, so that the support area at the bottom of the charger body 1 is larger, ensuring stability.

[0025] Furthermore, the charger body 1 has a sliding connection of a plug rod 9 inside, and a slot 10 is opened inside one of the second rotating rods 6. The slot 10 is used in conjunction with the plug rod 9. When the first support plate 4 and the second support plate 5 are both unfolded, in order to prevent them from automatically deforming and retracting, the plug rod 9 and the slot 10 limit one of the second rotating rods 6.

[0026] Furthermore, a baffle 11 is fitted on the outside of the plug rod 9 and between the charger body 1 and the second rotating rod 6. The baffle 11 is fixedly connected to the plug rod 9. A spring 12 is fitted on the outside of the plug rod 9 and between the charger body 1 and the baffle 11. One end of the spring 12 is pressed against the charger body 1, and the other end is pressed against the baffle 11. The elastic force of the spring 12 makes the plug rod 9 tend to move closer to the second rotating rod 6, which is conducive to the automatic engagement of the plug rod 9 and the slot 10.

[0027] Furthermore, a pull rod 13 is fixedly connected to the outer end of the insertion rod 9 away from the spring 12. A groove 14 is provided inside the pull rod 13, which makes it easier for the user to pull the pull rod 13. By pulling the insertion rod 9 with the pull rod 13, the insertion rod 9 is separated from the slot 10, thereby releasing the restriction on the second rotating rod 6.

[0028] The usage steps of this utility model are as follows: When using this mobile phone charger based on the flyback topology, after the mobile phone is finished charging, if the user needs to use a mobile phone stand while watching videos on the mobile phone, they can directly unfold the first support plates 4 on both sides of the charger body 1. When the first support plates 4 unfold outward, it will drive the first rotating rod 3 and the second rotating rod 6 to rotate outward. When the first rotating rod 3 rotates outward, it will drive the second support plate 5 below the first support plate 4 to rotate outward through the first gear 7 and the second gear 8. Since the unfolding of the first support plate 4 can expand the bottom support area, the second support plate 5 can further expand the bottom support area as it rotates outward. Finally, insert the plug 9 into the slot 10 on the second rotating rod 6, put the mobile phone into the mobile phone card slot 2, so that the charger body 1 can be used as a mobile phone stand.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
